To exploit the vulnerability, the attacker needs to know the business process and the internal network structure that is not easy to discover by accessing the URL directly. To avoid the risk of SSRF, you should use dynamic filtering for URL parameter validation. Moreover, the RAVA certificate validation system has insufficient input validation for RAVA domain validation. An unauthenticated remote attacker can perform injection attack to obtain RAVA domain validation. Hence, the attacker can obtain RAVA domain validation certificate and RAVA domain validation system can be used for malicious activities.
To avoid the risk of SSRF, you should use input validation for RAVA domain validation. Moreover, the RAVA certificate validation system has insufficient authorization for RAVA certificate validation system. An unauthenticated remote attacker can perform injection attack to obtain RAVA certificate validation system. Hence, the attacker can obtain RAVA certificate validation system and RAVA domain validation system can be used for malicious activities.
Risks and mitigation
If the RAVA domain validation system is exploited, a remote attacker can obtain RAVA domain validation certificate and perform malicious activities.
To mitigate the risk of SSRF, you should use input validation for RAVA domain validation. Moreover, the RAVA certificate validation system has insufficient authorization for RAVA certificate validation system. An unauthenticated remote attacker can perform injection attack to obtain RAVA certificate validation system. Hence, the attacker can obtain RAVA certificate validation system and RAVA domain validation system can be used for malicious activities.
RAVA Certificate Validation System
RAVA certificate validation system is used to identify certificates that are trusted in order to verify the validity of a digital certificate. The RAVA site uses an authentication server for authorization. However, the authentication server lacks input validation for RAVA domain validation. An unauthenticated remote attacker can perform injection attack to obtain RAVA domain validation through exploitation of this flaw. Hence, the attacker can obtain RAVA domain validation certificate and RAVA domain validation system can be used for malicious activities.
